摘要: Within the period from 2003 to 2005 (high water, normal water and low water) 63 samples are collected measurement of 10 chemical variables Yellow River Gansu period, carried out. These dissolved oxygen (DO), demand (COD), non-ion ammonia (NH x ), volatilization Hydroxybenzene (OH), cyanide (CN), As, Hg, Cr6 + , Pb, Cd. For handling results all measurements different chemoinformatics methods employed: (i) The basic statistical that uniform design is employed determinate data set according quality standard, (ii) MLP neural network (BP) Probabilistic networks (PNN) used classify sampling site time. correlation between classes sought. model built, these models could quickly, completely accurately River.
